Actually, there is at least one club I go to but rarely - because it is non-smoking. I don't smoke, but my late wife did, and I prefer to go to a club without that piety.

Another club I never went to (it has closed) made a big thing about how good the performers there were, and wanted you to ring in advance to book your spot (if they approved of you). This was no use as getting my wife anywhere on time was tricky, and anyway if her breathing problems were bad that night we would have to cancel.

Another club I don't go to, the organisers disappear to the bar (elsewhere) while anyone but a paid guest is on. And the audience sit there quietly during chorusses.

Another club I don't go to much calls itself a folk club but the majority of the stuff heard there is country or close to country.

Another club I don't go to has pretty much only paid guests (mostly doing American material), and the residents fill up most of the floor slot(s). Even when there is no guest they still do so. Joining in on chorusses gets you stared at.
